even in 10y h2 is economically unviable. Check out Norway/Sweden, they got tons of ren. Are they some _cheap_ H2 generation meccas? There are some chances for other synth fuels but H2 is just a pipedream

Norway and Sweden have tones of renewable energy, but relatively little intermittent energy. If the economics of H2 ever work, it'll only ever work in a grid that's driven by intermittent energy sources (wind and solar).

A hydro-driven grid does not need storage. Hell, if you have enough hydro, it can even be your storage. Not all of Europe has the geography to be able to cover their needs with just hydro.
